Question

What is the most efficient way to calculate the least common multiple of two integers?

I just came up with this, but it definitely leaves something to be desired.

Answer 1

There is no way more efficient than using a built-in function!

As of Python 3.8 lcm() function has been added in math library. And can be called with folowing signature:

math.lcm(*integers)

Returns the least common multiple of the specified integer arguments. If all arguments are nonzero, then the returned value is the smallest positive integer that is a multiple of all arguments. If any of the arguments is zero, then the returned value is 0. lcm() without arguments returns 1.
